• Writing auxiliary axis parameters to MR-J2-CT
After backing up the auxiliary axis parameters in the SRAM, turn the CNC and MR-J2-CT power
OFF, and replace the MR-J2-CT amplifier.
Initialize the replacement amplifier beforehand.
After replacing the MR-J2-CT amplifier, turn the CNC and MR-J2-CT power ON. Write in the
auxiliary axis parameter data and restore the absolute position.
The data in the CNC SRAM is written to the new amplifier.
The following describes the procedure for writing the auxiliary axis parameters to MR-J2-CT.
Input "(2) (a)" from the BACKUP screen. (a: axis No. (1 to number of connected axes))
After inputting, the message "CONTINUE Y/N" will appear for confirmation of the data backup.
The auxiliary axis parameters are written to MR-J2-CT only if "(Y)" is input.
The message "WRITE COPLETE" will appear when the writing operation is finished.
If MR-J2-CT is not connected, the message "E01 SETTING ERROR" will occur, and the data
will not be written.
Auto-tuning parameters are written as shown below, using the auto-tuning selection (parameter
#7 ATU) of the SRAM data and the MR-J2-CT side.
(Note 1) Which parameters can be input depends on the setting of "#7 ATU" parameter.
(Note 2) The CNC does not hold the MR-J2-CT parameters.

Refer to "2.6.2.7 MR-J2-CT parameters and N No. correspondence table" for details on
auto-tuning target parameters.
The parameters are held on the MR-J2-CT side.
When the MR-J2-CT unit is replaced, the parameters must be set again in the new unit.
